Its just a game that is not so very hard, but some battles are very violents, like when you fight gigants they die and are so freaking. And there´s also a female character that tries to seduct your character with "sexy movements" and she said that she can go to hers " true self form" with true love.
First of, yes it is VERY difficult. The game tries as hard as possible to be easy. It is almost impossible for newbies to get a hang of things. With that being said, Players that are good with patapon 1 or 2 will have no problem adapting. Second (minor spoilers) there are 7 dark heroes that each represent one of the 7 deadly sins. One character (naughtyfins) is very seductive and tries to manipulate the hero with her beauty but (MAJOR spoiler) can be changed back to her previous self with true love.
